Abstract: The invention provides a machine for grinding tree stumps to a level below the surface of soil in which the stump is located.   The machine comprises a sled structure including lugs for releasably coupling the sled with pivot pins to a moveable boom of a backhoe or other earth moving machine.    The sled has  skids or skiis  for guiding the apparatus over the surface of soil adjacent to the stump with the moveable boom.  A drive unit is mounted on the sled having  power  transmission  and  a  self  contained  fuel source.  A stump grinding wheel is journaled to the sled for rotation about a substantially horizontal axis and coupled to the power transmission of the drive unit.  The wheel has a stump abrading surface with replaceable teeth which shred, chip or grind the wood of the stump and dig a trench in the soil approximately 6-9 inches deep.   Preferably, the sled comprises a rectangular platform and two elongate skids each extending downwardly from one of two opposing sides of the platform thereby defining an inverted channel shaped sled having a forward and a rearward open end.  The grinding wheel is mounted between said skids with the axis transverse to said opposing sides.   A guard flap is hinged to the platform covering at least one open end, and the skids have planar inner surfaces to contain the spewing of wood and soil particles caused by the stump grinding operation.

Abstract: A device (10) is disclosed including a shelf (80) mounted to a lift tube (76) of a lift sub-assembly (74). An adjustment cone (88) is secured to the lower end of a rod (86) having its upper end pivotably secured to a handle (82) in turn pivotably secured adjacent the upper end of the lift tube (76).  The lift tube (74) is slideable in cylindrical inner surfaces (58) of top and bottom bushings (50, 68) separated by positional spacers (66) having inner surfaces spaced from the lift tube (76). Indexing spacers (26) are slideably received and stacked end-on-end inside a vertical tube (18) below the bushings (50, 68) and the positional spacers (66).  The lower ends of flexible fingers (92) of the adjustment cone (88) abut with an annular shoulder portion (36) formed in each of the indexing spacers (26) when the adjustment cone (88) is in its extended position relative to the lift tube (76) to prevent vertical movement therebeyond and allowing the ends of the fingers (92) to move in a circular path on the annular shoulder portion (36).  In the retracted condition of the adjustment cone (88), the fingers (92) are pulled partially inside the lift tube (74) to a size which passes through the annular shoulder portions (36) without abutment.  In the preferred form, the fingers (92) have a size which prevents passage through the cylindrical inner surface (58) of the bottom bushing (50) to prevent removal of the lift sub-assembly (74) from the vertical tube (18).

Abstract: The invention aims to make outdoor structure such as gate post suitable for mass production by achieving weight reduction of such structure so that the structure can be manually  transported,  installed,  on  one  hand,  and by facilitating adhesive fixation of artificial stones,  on the other hand.    A substrate 10 of a gate post A is molded from foam plastics  and  a  nail  21  is  partily  embedded  in  each artificial stone 20 during a process of molding this stone 20 so that the nail 21 may partily project out from  the rear surface of the artificial stone 20. Adhesive mortar is applied to the substrate 10 and/or the artificial stone 20 and then the artificial stone 20 is pressed against the substrate  10  so  that  the  nail  21  may  penetrate  the substrate 10 and thereby the artificial stone 20 may be adhesively  fixed.  In  this  manner,  the  gate  post  A  is effectively weight-reduced and the nail 21 is held by the substrate 10 under an elasticity of the foamed plastics until the adhesive mortar 23 is set. The artificial stone 20 is prevented by such provisional fixation from scaling off or falling off and there by production is facilitated.

Granted: 1999-09-21
Abstract: A foamer nozzle assembly has a foaming barrel defining a turbulence chamber for creating foam upon actuation of the trigger of a trigger sprayer as the conical spray impacts against the smooth inner surface of the barrel as so to emerge as loosely compacted, large foam bubbles having a relatively wide foam spread. A foaming grid in the form of an offset rectangular mesh screen is mounted on a hinged panel for movement between operative and inoperative positions. In the former the grid lies coaxial with the discharge orifice and provides a supplemental foam generator for breaking up the foam bubbles into finer and more concentrated foam having a relatively smaller foam spread. The grid comprises first and second sets of ribs lying in first and second parallel planes, the ribs of the first set being contiguous to the ribs of the second set, and they ribs being mutually spaced apart to define uniformly sized openings therebetween. The ribs of both sets have flat surfaces facing upstream and lie perpendicular to the central axis of the barrel.

Abstract: A recombinant DNA containing a sequence (1) coding for a polypeptide heterologous to a filamentous haemagglutinin of Bordetella (Fha) fused within the reading frame to a sequence (2) located upstream from the first sequence. Sequence (2) codes for at least part of the Fha precursor, which part comprises at least the N-terminal region of a truncated mature Fha protein, which contains the interaction site of Fha and heparin and the secretion domain. This Fha protein is under the control of a promoter recognized by the cell polymerases of B. pertussis and is inserted into a B. pertussis cell culture, is expressed in the culture and excreted into the cell culture medium. The invention uses both the abilities of Bordetella and particularly B. pertussis to secrete or surface expose the heterologous polypeptide fused to the Fha portion corresponding to sequence (2), which does not appear to produce extracellular proteases, and the ease with which filamentous haemagglutinins can be isolated from other Bordetella proteins.

Abstract: There is disclosed a device for measuring the magnetic field strengths associated with a.c. electrical currents over a protracted period of time and, as required, in hostile environments. A preferable application calls for the determination of the field strengths associated with electrical currents flowing in the a.c. power distribution lines of.utilities. The device includes a monitoring instrument positioned in relation to the power lines to be monitored, typically at the base of a pole immediately adjacent the pole of the power line or on a power line supporting pole itself. In order to provide for long term, powering of the monitoring device, d.c. power is developed utilizing the a.c. power that is present. The conversion from a.c. to d.c. is effected at a distance sufficiently far from the monitoring instrument so as not to have any consequence on the readings that are being taken. Readings during the protracted period are typically stored and then accessable at pre-determined periods. A device for checking the operability of the instrument is disclosed. A device for determining the lateral profile of magnetic field strengths for transverse distances from the location site of the monitoring instrument is also disclosed.
